Jack Antonoff, Bethany Cosentino, Jay Som & Rachel Brown Join Hayley Williams In Los Angeles

Hayley Williams brought the Hayley Williams At A Bachelorette Party Tour to Los Angeles Tuesday night and like other recent shows, the Paramore frontwoman was joined by special guests thought the performance. Jack Antonoff, Bethany Cosentino, Jay Som and Rachel Brown each took the stage alongside Williams at the first of three shows at the Wiltern Theatre.

Antonoff, the Bleachers frontman and accomplished producer, joined Williams for “Good Ol’ Days,” a track from her 2025 solo album, Ego Death At A Bachelorette Party. Williams debuted “Good Ol’ Days” live alongside Antonoff and Bleachers at a Rolling Stone Musicians on Musicians event at New York City’s Beacon Theatre last October.

Jay Som — the stage name of Los Angeles-based singer-songwriter Melina Duterte — performed her collaboration with Williams, “Past Lives.” The song appeared on Jay Som’s 2025 album Belong, which featured Williams on the track.

Bethany Cosentino, the Best Coast singer-songwriter who has been based in Los Angeles since the band’s formation in 2009, closed out the show with Williams on the album’s finale, “Parachute.” The song has become a recurring guest-spot feature throughout the Hayley Williams At A Bachelorette Party Tour.

Rachel Brown, vocalist of opening band Water From Your Eyes, joined Williams for “Discovery Channel,” reprising a role she has played at other stops on the tour.
